Detailed Description

As shown in fig. 1, the present embodiment has a grip 5, a hook blade 1 is provided at one end of the grip 5 through a blade link 2, a segment is provided at the other end of the grip 5, and a sword blade 10 is provided at the end of the segment, so that the needle knife is named as a beam sword crochet needle. The concrete structure is as follows:

the grip portion 5 is a cylinder 55mm long and 6mm in diameter, and is provided with knurling 6 on its cylindrical surface to enhance the frictional force of the grip. As shown in fig. 1 and 4, 2 holding surfaces 4 are arranged at a position close to one end of a holding part 5, and the holding surfaces 4 are long strips extending along the axis of the holding part 5, and have the length of 25-30 mm and the width of 12 mm; because 2 holding surfaces 4 are close to one end of the holding part 5, a cylindrical section of 20-30 mm is arranged between the end far away and the holding surface 4; the 2 holding surfaces 4 are arranged in a splayed shape on the section of the holding part 5, and the included angle of the 2 holding surfaces 4 is 35 degrees.

A 10mm long frustum 3 is arranged at one end of the holding part 5 close to the holding surface 4, a blade connecting rod 2 is arranged at the front end of the frustum 3, the head end of the blade connecting rod 2 is thinner, the tail end of the blade connecting rod is thicker, the tail end of the blade connecting rod is 1.5mm, and the head end of the blade connecting rod is 1 mm. As shown in fig. 2 and 3, the sickle part 19 at the head end of the blade link 2 is provided with a sickle-shaped sickle body 22 protruding transversely from the blade link 2, the top of the sickle body 22 is an arc-shaped top 27 having an arc shape from the front view and the bottom view, the sickle body 22 is provided with a horizontal blade 24 perpendicular to the axis of the blade link 2 and formed by intersecting two sickle blade surfaces 26 at the inner side of the sickle shape, the horizontal blade 24 is 2-3 mm long, the two sickle blade surfaces 26 are intersected with each other to form a longitudinal blade 23 connected with the horizontal blade 24 and parallel to the axis of the blade link 2, and the end of the sickle body 22 is provided with a sickle blade tip 25 formed by the arc-shaped top 27 and the two sickle blade surfaces 26. The distance between the sickle-blade tip 25 and the near end (namely the end adjacent to the sickle-blade tip 25) of the holding surface 4 is 45-55 mm, and the further long distance is not favorable for fine operation and exertion, and the too short distance is not favorable for the penetration depth of the needle end.

It should be noted that the longitudinal blade 23 protrudes a small distance (0.5 mm in this embodiment) from the blade link 2. The trailing edge 23 is provided to prevent the root of the chisel edge 24 from causing unsmooth and stuck cuts if the adjacent portion is not sharp when participating in the cut. And the longitudinal edge 23 protrudes a short distance from the blade link 2 to prevent the blade link 2 from blocking the longitudinal edge 23 to perform its corresponding function.

The sickle blade part 19 can also be used for the hook cutting of subcutaneous tissue adhesion on one hand, but the needle end is the arc top 27, so the sickle blade is suitable for the place with little obstruction of the needle inserting direction, and the sickle blade is suitable for the large-range adhesion of non-important parts because the feed amount of one hook cutting is large; on the other hand, the sickle blade 19 is mainly used for the longitudinal opening operation of superficial blood vessels, and the present embodiment is also named as the Liangshi embolectomy needle because all doctors believe that some emboli in the blood vessels block qi and blood circulation, and for the subcutaneous blocked blood vessels which show black purple color, a certain opening is broken along the longitudinal direction to expel the emboli, so that the focus can be eliminated. The sickle edge tip 25 is convenient for puncturing epidermis and subcutaneous vessel wall, the cross edge 24 vertical to the axis of the edge connecting rod 2 is convenient for controlling force and the direction of the knife edge, because the vessel wall has certain hardness, certain rapid force is needed when force is applied, on one hand, the patient is more painful due to too moderate force, on the other hand, the knife edge is easy to change the direction and deflect in the advancing process; compared with other oblique schemes, when the cross blade 24 is perpendicular to the axis of the blade connecting rod 2, when the cross blade 24 moves along the axis of the blade connecting rod 2, lateral component force cannot be generated to change the feed amount (for example, the blade slips off or moves towards a deeper part of a blood vessel until a side vessel wall is broken by a hook), a doctor can conveniently prejudge and control the trend of the blade by controlling the whole needle to move along the axis direction of the needle (actually, the axis direction of the whole needle), and the change of the feed amount cannot be caused. The length of the chisel edge 24 is 2-3 mm, so that the blood vessel wall breaking device can meet the requirement of breaking the blood vessel wall on one side of a superficial blood vessel, the blood vessel wall breaking device is not enough sometimes when the blood vessel wall is too short, the blood vessel wall breaking device is not favorable for controlling a needle knife because the chisel edge 25 is farther away from the axis of the whole needle when the blood vessel wall breaking device is too long, and the blood vessel wall breaking device is easier to hook on the other hand to break the two sides of the blood vessel wall and cause unnecessary excessive bleeding.

The reason that the needle body needs to swing to a certain extent in operation, the needle body far away from the hook edge part 1 is subjected to larger bending moment, and the edge part connecting rod 2 is properly thickened gradually to prevent the needle body from entering a human body in the operation process from bending, and because a doctor cannot observe the bending in the operation process, the doctor cannot effectively finish cutting according to the experience of using a normal needle body.

The operation of the sickle-blade 19 is mainly performed by the grip 5, and is therefore also very important for the operation. The two splayed holding surfaces 4 on the holding part 5 can enable a doctor to operate the needle knife in a pen-holding posture, and the pen-holding posture is more beneficial to the capability of accurately controlling the movement of the needle point of a person. The holding surface 4 can effectively prevent the needle body from rotating and slipping compared with the cylindrical surface, and the edge of the sickle blade part 19 is relatively fixed relative to the splayed arrangement, so that after a doctor proficiently uses the needle knife, the cognitive control on the overall posture of the needle knife can be improved, and the operation is convenient. The included angle of the 2 holding surfaces 4 is not too small or too large, and the direction of the splayed character is not easy to distinguish if the included angle is too small, and the force is not convenient to be applied downwards by the forefinger and the thumb; if the size is too large, the user will feel uncomfortable in the pinch posture, which will be described below, and the size is generally 30 to 45 degrees, preferably 35 degrees.

The holding surface 4 is long strip-shaped and extends along the axis of the holding part 5, the length of the holding surface is 25-30 mm, so that the holding method of attaching the thumb and the belly of a finger and clamping the middle section of the index finger can be conveniently used, the pen holding posture is that the thumb and the index finger tip are used for holding and clamping, the pen holding posture is laborious, and the clamping type is more beneficial to generating larger force. And because the holding surface 4 is close to one end of the holding part 5, a cylindrical section with the diameter of 20-30 mm is formed at the far end, and the cylindrical section is provided with the knurls 6, the cylindrical section can be clamped by a tiger mouth when the clamping posture is adopted, and the holding force is increased. And sometimes the treatment requires twisting of the needle to rotate it, and the cylindrical section with knurls 6 facilitates this operation.

Furthermore, the orientation of the sickle-blade point 25 (i.e. in the lower direction in fig. 1) corresponds to the splayed wide mouth orientation of the two holding surfaces 4, since the downward force of the sickle-blade point 25 is greater and easier to control than the upward force in the pen-holding position, and the downward force of the sickle-blade point 25 is advantageous for the operation of the needle knife.

In the embodiment, a segment part with the total length of 55mm is arranged at one end of the holding part 5 far away from the holding surface 4, the segment part is three segments, and a first segment 7, a second segment 9 and a third segment 20 are sequentially arranged from thick to thin. The total length of the three segments is 55mm, and too long is not conducive to operation. Wherein, the diameter of the first segment 7 is 4mm, the diameter of the second segment 9 is 3mm, the diameter of the third stage 20 is 2mm, and the tail end thereof is a circular arc surface 21, and the adjacent two are transited by a chamfer 8 and the total length of the segment part is divided evenly. The segment part is mainly used for defibering the adhesion parts of muscles, ligaments and the like of a patient, such as knee joint adhesion, after the knee skin of the patient is opened, the segment part is inserted, after the segment part is inserted to a focus, for example, the third segment 20 is inserted into the adhesion part between the fibula collateral ligament and other tissues, then the needle body is continuously pushed in, so that the thicker second segment 9 is inserted, the gap of the adhesion part is expanded, the gap between the fibula collateral ligament and adjacent tissues is continuously expanded and retracted after repeated drawing, the adhesion of the ligament and other tissues is gradually defibered and peeled off, and the focus is removed. The round arc surface 21 can ensure that the damage to normal tissues is minimized when the needle body is drawn, and is suitable for the condition that the needle body is easy to insert.
